Re^3: dbd odbc sql big file blues

[CaptainDaddy]

Here's a reproduction of the error

#
#
#connect to the database, set some properties
#
$host=...;
$port=...;
$user =...;
$pass = ...";
$dsn="dbi:ODBC:Driver=/usr/local/lib/libtdsodbc.so;SERVER=$host;PORT=$
+port;DATABASE=...;TDS_Version=7.2";
$dbh= DBI->connect($dsn,$user,$pass) or die "can't connect";

$fileTableName="fileTable";

$cmd="SELECT 1 FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_TYPE='BASE T
+ABLE' AND TABLE_NAME='$fileTableName\'";
$fetchcmd= $dbh->prepare($cmd);
$fetchcmd->execute();
if(@row= $fetchcmd->fetchrow_array){
    print "the file table is there!!!\n";
}else {
    $createCmd=$dbh->prepare("create table $fileTableName (fileColumn 
+VARBINARY(MAX) not null)");
    $createCmd->execute();
    $insertCmd=$dbh->prepare("insert into $configTableName (fileColumn
+) values (?)");
    $insertCmd->bind_param(1,0,DBI::SQL_VARBINARY);
    $insertCmd->execute();
}
$fetchcmd->finish();


$insertcmd= $dbh-> prepare("insert into $fileTableName (fileColumn) va
+lues (?)");

# 350kBites -> largest number is 2^(8*350000)-1
for($i = 75; $i<2**28000000;$i=$i*2){
    print"did";
    $insert='g'x$i;
    $insertcmd->bind_param(1,$insert,DBI::SQL_VARBINARY);
    $insertcmd->execute() or print" not ";
    $insertcmd->finish();
    $sz=length($insert);
    print " succeed. size: $sz\n"; 
}
$dbh->disconnect;

The above code gives me the following output:
